Polyethyleneterephthalate (PET) bottles have become one of the most valuable and successfully recyclable materials. The PET glycolysis products were used for the synthesis of saturated and unsaturated polyester, polyurethanes, coating materials, and additives. In this work, PET were depolymerized by glycolysis using ethylene glycol (EG), diethylene glycol (DEG), neopentyl glycol (NPG), and propylene glycol (PPG). The depolymerized products were analyzed by Fourier transform infrared spectroscopy (FT-IR) measurements, Gel permeation chromatography (GPC), and Gas chromatography/Mass (GC/MS). |
